Leicester City denied Frank Lampard a first win as Chelsea manager as the Foxes earned a 1-1 draw at Stamford Bridge on Sunday.
Mason Mount put the hosts in front in the seventh minute when he dispossessed Wilfred Ndidi in Leicester's penalty area and fired home a low line drive past Kasper Schmeichel.
U.S. winger Christian Pulisic went to ground near the end of the first half after awkwardly blocking a cross, but despite looking like he might have picked up an injury he was able to carry on as Chelsea took a 1-0 lead into the dressing room.
